Anyone who's had any exposure to the Lean Startup school of thought will know this idea already, so most people here will definitely know what you're doing.

As an aside - I detest being sent to a landing page that's clearly harvesting emails as a prelude to actually doing any real work on implementation, but maybe that's just me. Plausibly your implementation of this idea will be a real boon for someone wanting to try an idea.
Hey, really cool app. I am actually working on something similar. Would love to connect with you to talk shop. There could be some great synergies between what we are working on. Email me at davidmspi@gmail.com. Hope to hear from you soon!

Yes. There's even more non-bootstrap "admin themes" that suck too.
Leveraging the experience of many? I wan't my website to be fast. I don't have deep understanding on web optimization and don't have yet enough data or time to build my own solution. I search around in the web, and go to http://developer.yahoo.com/performance/rules.html. I trust them (yahoo) because them are probably more competent and have MORE DATA than me. I implement some of the ideas, get some results (and if I'm smart, get a clue on why are good ideas and how it affect the performance).

Acting in data IMHO is only if have LOT of data. If not, acting in expertise of others look best to me..
i agree the article got Mercedes costs wrong but your comment is on the other end of the spectrum. I've owned 2 Mercs and never had to run through 4 sets for 50k miles, 1 maybe 2 at most. But I do agree that merc dealers charge crazy for a service. I was once told to fork up $1600 for a full service. The local service shop charged me $150 for the same thing.

The article seems to suggest that BMW has a good new car warranty but Mercedes doesn't. All new mercs have 4 year, 50k miles warranty as well.
Ugh, now I'm convinced my next car needs regenerative braking.
The Model S is extremely simply from a drivetrain perspective. AC motor <-> energy transfer management <-> energy storage

Chevy Volt: AC motor <-> energy storage <-> onboard generator

So I can keep my Model S reservation and shell out $600/year on top of the $50K+ purchase, or I can purchase a Volt and have a generous warranty I don't need to pay extra for.

Hard choice for the practical among us.
Paypal have had their share of bad customer experiences. However it is clear in the Paypal policies that trusts are not allowed to own accounts. If someone was ignorant to not notice that, I believe it is unfair to point fingers at Paypal.
The current price of 1 BTC should be $2.50 USD
The real value of a currency depends on the value of the goods that can be purchased with it. If we assume the majority of bitcoin transactions for 'real' goods (not currency speculation) are on silk road we can do the following calculation.

The demand in USD is about 1.9 million per month (http://arstechnica.com/tech-policy/2012/08/study-estimates-2-million-a-month-in-bitcoin-drug-sales/) which works out to be $63,333 per day (the demand)

There are currently 10118337 bit coins that have been created and each coin is spent on average once every 399.357 days (http://abe.bitcoinstats.org:2750/)

This means that each day there are 10118337 / 399 = 25,359 bitcoins available to use for transactions each day (the supply)

The price of 1 BTC should then be supply / demand = $63,333 / BTC 25,359 = $2.49 USD per coin

Does anyone have alternative suggestions for calculating the price?
I understand why not to use early exits. But what's wrong with early returns?

Managing your child's stress
Wayne,

Yeah sorry, that did sound smug, but I didn't mean it to be. It was internal amusement at the stuff the tinfoil crowd comes up with that probably should have stayed in my head rather than ending up in an HN comment.

Thomas,

It's smug because he has professional experience with the topic and few others here do. From previous comments: 'runjake is in his 40s, served in the military (I'm presuming the USAF)

Yep.

did EE/CS stuff with the ICBM program, and did some kind of work the UAV control system

Yep, but I wasn't in the ICBM program, rather I worked with air-launched/dropped nukes. I did not work directly on any modern UAV systems. I worked with their 1990s precursors: air-launched autonomous (conventional/nuke) cruise missiles.

It is possible that he is just making that stuff up, but it's (a) unlikely and (b) pointless and boring to debate it.

Yep.
I really don't think they're worth what some think or what they used to be as it's getting kinda common to see other TLD's as a company's main domain.

You didn't actually correct or refute any facts, which makes me rather suspicious of your authenticity. Possibly you rephrased the semantics of 'stole' in the context of strong arming the enemy at the time.

It's common knowledge that many of Braun's team ended up at US defence contractors, it wasn't just military but also space exploration that benefited from their rocketry knowledge.

I'm actually Portuguese, the only people I know that managed to do that, were guys and girls from my degree doing something on the side during the .com days for some startups, back in the 90's.

The problem is, it's always in the form of "x + y = ?", which makes it ridiculously easy to bypass with an script.

At least that's what I initially thought. But after some more digging it seems that x and y are hard-coded to be 2 and 3, respectively.

I opened the registration page in 4 different browsers with different IP addresses (my own, my VPS, and a couple borrowed from Tor) and in all cases the "security" question was "What is 2 + 3?"

Unbelievable.
Hi Colin. Yes I agree it's a fine balance between not having a product and pretty much spamming and wanting to get out of the door with something that could be really valuable to a lot of people.

I've found that the service is really useful to those who wouldn't be able to test their ideas (not technical, not enough time etc) and I know a couple of projects that have come out of it so far that look really good. So have faith.

Mm that's a good point though, perhaps I could include something about it being suitable for 'lean startups'. Is that copyrighted I wonder?
When I first learned about this investment problem (although, my version had 18-30 and 30-65), I worked out the math, and I think it held for as low as 2% interest. I could be remembering wrong though... Surely, someone's done a formal write up on this?

You're talking yout of your ass. In preparation for vietnam, the US armed forces studied lethality of intent for small arms fire. Vietnam was the dataset, which has since been further validated. The cited text was written by a professor at west point, he's not full of shit.

Data (roughly) for effectivenes / lethal intent:

Population (normal): 5%

Soldier (WWII era): 20%

Soldier (Current Era): 95%

These are anectdotally referenced in the linked article, but they are discussed in that article's main citation, which is here:

Publication Date: November 1, 1996 | ISBN-10: 0316330116 | ISBN-13: 978-0316330114 | Edition: 1

[Amazon.com] Lt. Col. Dave Grossman draws unsettling, even sinister parallels between the psychological conditioning required to make soldiers kill in war and the similar effect that videos, films, games and movies have in civilian society.

This book is/was a textbook used in the armed forces, it is a summary of working papers etc. It is not some BS handwavey claptrap from academia. What you will notice from reading it is it is actually very difficult to get people to Kill one another.

That is why the data on effectiveness are so damning.
I get your point, but you should remember that we all have learned things the "wrong" way for the sake of brevity before we moved on to learning the best way. Despite the flaws, I still think the tutorial is a great introduction to breaking down the steps of creating a game.

Nothing I said wasn't already public knowledge, fwiw. A lot of this info is in Ben Rich's book, amongst others. My acknowledgement of Project Paperclip (which has been a dead horse beaten) pretty much refutes the "stole" part I was referencing. But maybe I've been reading too much about Apple vs. Samsung to know what the true definition of "stole" is, anymore.

Yes, but that would be assuming that salaries have a market value.

In Spain salaries are often raised by collective bargaining. I don't know how much an effect it has on software developers, but the law is intended to raise the minimum salary for junior developers thus reducing the possibilities for a consensual agreement on a low salary.

Similar for holidays, working hours, etc.
Thanks for the link, it was PreScheme I was thinking of. You can make a PreScheme to native code compiler. Portable Standard Lisp also uses the same approach now (PSL->SYSLISP->C), but I think when it started out it may have compiled to machine code.
There are already many vehicles that will do far over 55mpg on a "fossil fuel" powered engine. Unfortunately, higher mpg = higher carbon emissions. As long as the Govt and Oil industries control environmental regulations, they can easily control maximum mpg by regulating how much emission can come from the engine (and thus, how efficiently the engine can burn gas).

Simple logic, theyre just hoping everybody keeps buying the environmentalism sales tactic so they can continue to force us to buy electric cars or low mpg cars. You are either buying their lithium, or overpaying for their gas...
I agree with you.

However, there is a difference between having been taught something, knowing about it, and having the information available in instant recall. For example, the B-tree question. three possible thought processes for this question (forgive me for my all-male cast):

Alan thinks, "Hmm. Well, they're both trees, but I don't really remember that difference. Maybe a BST is optimized for binary search, hence the name? This is a waste of time, I'll google it. Oh, of course, now I remember."

Bob thinks, "What!? What are trees!? Like outside? Oh no. Oh no oh no oh no. I remember what binary search is but how does it apply to a tree? Oh geez :("

Carl thinks, "A B-tree is a generalization of a BST, nodes in a B-tree can have more children than a BST"

Alan is probably a typical software developer with experience who might or might not have a degree but has been exposed to concepts. Bob is a college sophomore or someone who was never exposed to algorithms and doesn't have the background to even grapple with the question. If he googles for the answers, he'll be able to write them down but won't be able to relate them to other concepts or incorporate them into his mental model.

Carl just wrote a B-tree. Maybe Carl is a college senior, maybe a senior computer scientist at IBM.

in my opinion, you want people like both Alan and Carl. There are probably a lot more Alans than Carls. Hiring either is probably fine. There are probably a lot of Alans reading the OP, they probably won't be too upset about not knowing these off the top of their head because they know that they can refresh their memory on demand. Or maybe this is just my apology for my own mediocrity, because I had very few Carl level responses to the OP!

the problem I recognize is differentiating Alan from Bob. It's harder. If you only take the Carl responses to these questions, you'll draw only from a pool of smart people. If you start to allow Alan-level responses to be acceptable, you could also get a Bob. That would be bad.

Why do you say Google killed Reader? It may have moved down in the menu hierarchy, but it works fine still. They did, however, kill the project that allowed you to subscribe to html instead of RSS and google would compare versions of a page and generate RSS of differences, possibly that's what you were thinking of.

If we are in a situation where we are unable to collect the data in the first place

that's mischaracterising my point. I didn't say anything about having no data. I talked about when the data you're able to get is unrepresentative.

from what place did these putatively superior data or opinions come from? Because they clearly aren't coming from data.

i think that's just playing word games with "data". We're talking about data concerning the problem at hand. Theories may come from data, but they don't come from data you obtain about the problem at hand. And knowledge can come from experience, which again is a form of data, but clearly not the sort the person was talking about. You can reason based on knowledge and principles.

Sure, it'd be better if you had good data, but when you can't have that sometimes the best you can do is to reason based on knowledge/experience/theoretical ideas.
IANA Automotive Engineer, but I notice that while much breaking happens below 10mph (everytime you come to a stop from any speed, you're doing some breaking under 10mph, right?) break pads are likely to get worn far more at higher speeds - kinetic energy depends on the square of the speed, right? So decelerating from 35mph to 10mph, the break pads need to absorb (for some k) k * 35^2 - k * 10^2 units of energy, while decelerating from 10mph to 0mph is k * 10^2. The difference is more than an order of magnitude, and it only gets bigger as the speed increases. This doesn't even take into account all the times we slow from 35mph to 25mph, which is about 6 times as much energy as slowing from 10mph to a stop.

Europe has been moving in that direction, with an increase in biking, and improvements in biking infrastructure even in countries that weren't traditionally very bike-friendly (like Spain). But it's hard to replicate that in the U.S. because the cities are so much less compact. You would need more than just improvement in roads, but shorter distances, and better transit for the places where you do have longer distances. In the suburb I grew up in, my dad drove 50 miles roundtrip to get to work, the nearest grocery store was 3 miles away, the nearest restaurants/bars were 5 miles away, and there was no transit system at all. So biking tended not to be too popular, except among kids going to friends' houses within the same neighborhood.
That isn't a misspelling, but a very common shortcut. I fail to see how this in any way detracts from the readability of the text. Other shortcomings notwithstanding, "pls" is fine for the vast majority of internet users.
Practice is a good habit. I like to warm up in the mornings with a code-kata problem before I start my day. Just take a trivial problem and write a program to solve it. Take the same problem on another day and solve it a different way. Contrast the results of the two approaches. Think about which approach felt more natural, which one was most efficient, in what real-world cases would you choose one approach over the other... in other words, reflect. Practice without reflection is meaningless repetition.

If the goal is to be able to invoke a method on an object without checking for anything other than whether a method with the correct signature exists, that isn't a feature that's supplied by dynamic typing. It's supplied by duck typing, which is yet another axis (alongside dynamic/static and strong/loose). A popular example of a statically typed language that has had duck typing for a very long time is Objective-C.
Going off-topic, what would a good "computer science for the general public" article look like to you? I imagine it would not be about something new, but something well-established and how it relates to the real world. Eg, the principles of process control as applied to logistics.
Looking forward to the SpaceX update.

One of the things that struck me is that trying to watch the control room at the same time as this anomaly I have yet to pick out anyone who 'flinched' or made any sort of noted move. That has left me wondering if they knew when this happened that it happened. I have to believe they did.

I remember watching the faces of the people in the control room when they did TV shots of the control room of NASA and noting that there was always someone who knew that things weren't going to plan, their face betrayed that knowledge.

That said, it looks like their primary cargo was fine, but they ended up putting their secondary cargo into a 'backup' orbit.

After reading the review I was afraid that it was going to be primarily about in-game action - but was relieved when I read it that the online game was mostly a backdrop and only a few scenes actually occur there. I absolutely recommend this book to anyone who has played a MMORPG for more than a few hours and enjoyed the concept of it - even if you were never addicted. It is not a masterpiece like Cryptonomicon or Anathem but a very enjoyable read.

One way to simplify the problem is to figure out how much interest income the "early investor" is making at the moment the "late investor" kicks into gear. Obviously if Jane invests from age 16-20 and is now rolling $4,000/yr interest income back into the mix on her 21st birthday, John's yearly contribution of anything less than $4,000 ain't gonna cut it.

The Rule of 72 http://en.wikipedia.org/wiki/Rule_of_72 is a really handy tool the layperson can use to get a grip on how long it takes for compounding increases (which is most increases we deal with day to day--taxes, population, traffic) to result in doubling. It makes a much greater impact to say "this town's population will double in 10 years" than it does to talk about 7% growth rates.
